RJ-45 termination with CAT 5, CAT 5e, or
CAT 6 cable must comply with the TIA/EIA T 568A or
TIA/EIA T 568B wiring standard for all connections.
Figure 2-20 details the recommended termination of TP cables
with RJ-45 connectors in accordance with either the
TIA/EIA T 568A
or the
TIA/EIA T 586B
wiring standard.

Do not use Extron’s UTP23SF-4 Enhanced Skew-Free
™
A/V UTP cable to link the transmitter and receiver.
Skew-free A/V cable was designed for most Extron
TP transmitter/receiver applications, but the
HDMI 201 Tx/Rx does not work properly with this
cable.
N
In order to fit in the junction box, the TP cables and
RJ-45 connectors should not have a boot installed.
N
If necessary, test for proper cable connection (output 1 to
input 1, output 2 to input 2) as follows:
1
. Plug both TP cables into the powered unit.
2
. Momentarily connect either of the cables on the
opposite end into the unpowered unit‘s “2” connector.
If the unpowered unit’s Power LED is lit
, the
connection is correct.
If the unpowered unit’s Power LED is not lit
,
unplug the connector on the unpowered end and
connect the other cable to the “2” connector.
